Eastern Ont | For the most part happy timer is bang on with his comments. I would call them "best practices" to have the greatest success with Liberty...but for sure if the field is ready for weed control and you have lots to do then you would need to spray anyways and not wait for the perfect environmental conditions.
Liberty link canola has been around for more than 10 years, so I have some experience with Liberty too.
From the canola council website:
Liberty herbicide and registered mixes can be applied to Liberty Link varieties.
Controls various annual grassy and broadleaf weeds, and suppresses some perennial weed species.
Liberty works best when applied with water volumes of 10 gallons per acre.
Applied post-emergent. Activity is through contact with green tissue, with affected plants show burning/yellowing within 2 to 5 days after application. Plants die one to 2 weeks after treatment.
Unique mode of action (Group 10) and can be tank mixed with Group 1 clethodim. Good option for grassy and broadleaf weed resistance management.
No restrictions on recropping in the year following application
Liberty works best on warm sunny days. On cloudy days, increase water volumes and consider spraying later in the day when temperatures are at their highest.
Liberty is registered for aerial application. Centurion and Select are also registered for aerial application.
Avoid spraying Liberty when temperature are above 28 C as canola injury can occur.
